I ran into the same problem with saves. The Alpha and Beta releases of day 10-11 did not locate saves I had made in Week 1, so I created several new ones while playing those, but now when I load this new release, my Week 1 saves are there, but my saves from days 8-11 are not. When I load the old week 1 saves they always skip to the beginning of Day 8 (in German for some reason).
If you played the alpha and/or beta releases and have saves, it looks like you can move those to a new folder, rename them as needed, then import them back and they work. ¯\_(ツ)_/¯
